Here's the dirty secret of SLR cameras: they get dirty. More specifically, the CCD or CMOS sensors get dirty. Depending on the kind of camera you have, your camera will have either a CCD (Charged Couple Device) or the CMOS (Complementary Metal-Oxide-Semiconductor), which is the device in digital cameras that acts as the film and receives the image. In normal operation, the sensor develops a high static charge, and if there is any dust near the sensor, the dust will get attached to the sensor by static electricity. If you can cope with the costs and have a delicate touch, you can do a great job of cleaning your camera's sensor with the VisibleDust system.
